No Mouth and a Short Life
Adult Atlas moths do not feed. They live for only about one to two weeks, relying on fat stored by the huge caterpillar. The female releases pheromones that males detect with feathery antennae from far away.
Snake-Head Wingtips
The tip of each forewing resembles the head of a snake, complete with an eye-like patch, an example of mimicry that may scare off predators. In some places, the moth is called the snake's head moth.
Silk and Culture
The large cocoons produce a coarse silk called fagara silk. In Taiwan, empty cocoons are used as purses.
